Abstract

In this letter, a compact tunable lumped-element Wilkinson power divider is proposed.It is realized by the electronically tunable microwave impedance transformers controllable by varactor diodes. The proposed divider possesses a tunable frequency range over a bandwidth of 53% different from the conventional Wilkinson power divider. Experimental results show that it can operate over the tunable frequency range from 1.1 to 1.9 GHz with more than 50 dB isolation between the isolated ports. © 2010 Wiley Periodicals, Inc.
